Acoustic rhinometry (AR) is a new, objective method for evaluating the geometry of the nasal cavity, the cross-sectional area and the nasal cavity volume. 36 patients with septal deformities were examined with AR. The values were compared with those of 21 normal controls and also the comparison was made pre-operatively and post-operatively in 18 patients undergoing septoplasty. The results showed that the minimal cross-sectional area (MCSA) was located in the anterior part of the nasal cavity corresponding to the area causing main nasal airway resistance (NAR). After septoplasty, increased MCSA with decreased NAR indicated that MCSA might reflect the state of nasal ventilation function properly, while the nasal cavity volume seemed not to be a sensitive parameter for evaluating nasal ventilation function. As the sensation of nasal airflow presents a different entity than NAR, the interpretation of the results of acoustic rhinometry and rhinomanometry, and the relationship with the subjective symptoms should be made with caution. The choice of surgical indications and the evaluation of medical effect should be made according to both objective examination and subjective symptoms.
鼻声反射（AR）是一种用于评估鼻腔几何形状、横截面积和鼻腔容积的新型客观方法。对36例鼻中隔畸形患者进行了鼻声反射检查。将这些值与21例正常对照者的值进行比较，并对18例接受鼻中隔成形术的患者在术前和术后进行了比较。结果表明，最小横截面积（MCSA）位于鼻腔前部，对应于引起主要鼻气道阻力（NAR）的区域。鼻中隔成形术后，MCSA增加而NAR降低，表明MCSA可能恰当地反映鼻腔通气功能状态，而鼻腔容积似乎不是评估鼻腔通气功能的敏感参数。由于鼻气流感觉与NAR呈现不同的实体，因此在解释鼻声反射和鼻阻力测量结果以及与主观症状的关系时应谨慎。手术适应证的选择和治疗效果的评估应根据客观检查和主观症状两者来进行。
